“…Regarding XPS spectra of the Ag 3d region (Figure 3(b)), two emerging peaks were located at 367.4 eV and 373.4 eV, which are assigned to characteristic binding energy of Ag 3d 5/2 and Ag 3d 3/2 spin states [29]. As proposed in previous studies [8,30,31], these peaks with a distance around 6 eV originated from Ag nanoparticles 2…”

In this work, we successfully fabricated homogeneous hydrothermal titanate nanotubes (TNTs) coated with Ag nanoparticles (NPs) and elucidated the role of Ag NPs on local surface plasmonic resonance, surface-enhanced Raman scattering, and the enhanced photocatalytic activity of TNT/Ag nanocomposite. The results showed that the photodegradation process reached equilibrium in just ~5 min for the TNT/Ag nanocomposite, which was much shorter than that of the TNT sample (~90 min). TEM micrographs showed that Ag NPs were well dispersed on the walls of the nanotubes. XRD patterns and Raman spectra indicated that the TNTs were in the monoclinic structure of H2Ti3O7. Furthermore, Raman active modes of the TNTs were significantly enhanced in the TNT/Ag sample, which was attributed to surface-enhanced Raman spectroscopy. The enhanced photocatalytic activity of the TNT/Ag sample was explained by UV-vis diffuse reflectance spectroscopy and photoluminescence emission spectroscopy, which showed local surface plasmonic resonance-induced visible light absorption enhancement and effective charge separation, respectively.

With the advancement of applications in biomedicines and bioelectronics, conducting polymers have attained huge significant attention. For such applications, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is considered a potential conducting polymer because of its low cost, considerable stability, high conductivity and mechanical strength. Most importantly, its easy aqueous solution processability makes it more attractive. Over the last few years, PEDOT: PSS has been predominantly explored and investigated for different optoelectronic flexible devices, and recently it has been studied for biomedical applications.PEDOT:PSS based materials have made progress in biomedicines due to their properties such as biocompatibility, cell proliferation, antibacterial, nontoxicity and so forth. To adjust the desirable properties, special attention is required for altering the structure of PEDOT:PSS material. PEDOT:PSS offers excellent antibacterial properties against both gram-positive and gram-negative bacteria. Moreover, PEDOT:PSS demonstrates an important role in sensing human body humidity, pressure control, glucose detection, as well as employed in human sweat sensors. Besides these, PEDOT:PSS has been studied as a scaffold for endothelial cell preservation. There are several issues which need to be resolved in the future, such as improved biocompatibility and stability to explore the PEDOT:PSS based composite materials in biomedical applications. However, a related review article is lacking, directed on the PEDOT:PSS biomedical applications, namely, antibacterial, tissue engineering, and biosensing. Therefore, the current article summarizes importance of PEDOT:PSS for biomedical applications, and main emphasis is given to its recent advances, challenges and perspectives.

“…On one hand, enormous efforts have been made to modify TiO 2 to enhance its visible light absorption ability, including element doping, noble metal loading, combining TiO 2 with other semiconductors, and narrowing the bandgaps of TiO 2 . [12][13][14][15] On the other hand, great achievements have also been made in the exploitation of novel visible-light-driven photocatalysts.

Semiconductor photocatalysis technology is considered to be a promising technique to solve increasingly serious environmental pollution. Metallic bismuth (Bi)‐based photocatalysts have received much attention due to their extensive applications in environmental remediation because metallic Bi can function as a cocatalyst or a direct plasmonic photocatalyst to accelerate the photogenerated charge separation and thus improve their photocatalytic activity. In the last decade, enormous efforts have been made to seek excellent metallic Bi‐based photocatalysts as well as reveal the corresponding photocatalytic reaction mechanism for the degradation of organic pollutants in water. Herein, the unique electronic and optical properties and main synthesis methods of metallic Bi, as well as the detailed strategies and technology routes are timely summarized and discussed to enhance the photocatalytic activity of metallic Bi‐based photocatalysts in water purification. Finally, the future development and challenges of metallic Bi‐based photocatalysts are briefly discussed, summarized, and prospected.
